Posted 2021-02-07 eastonliu

postman常见断言方法介绍：

1、Clear a global variable (清除一个全局变量) 

postman.clearGlobalVariable("variable_key");

2、Clear an environment variable (清除一个环境变量)　　

postman.clearEnvironmentVariable("variable_key");

3、Response body:Contains string (返回消息体中包含某个内容)　　

tests["Body matches string"] = responseBody.has("string_you_want_to_search");

4、Response body:Convert XML body to a JSON Object (将xml格式转换成json格式)　　

var jsonObject = xml2Json(responseBody);

5、Response body:Is equal to a string (返回的消息体等于某个字符串)　　

tests["Body is correct"] = responseBody === "response_body_string";

6、Response body:JSON value check (json值校验)　　　　

var jsonData = JSON.parse(responseBody);
　　tests["Your test name"] = jsonData.value === 100;

7、Response headers:Content-Type header check (检查消息头中是否有某个字段)　　

tests["Content-Type is present"] = postman.getResponseHeader("Content-Type");

8、Response time is less than 200ms (响应时间判断)　　

tests["Response time is less than 200ms"] = responseTime < 200;

9、Set a global variable (设置全局变量)　　

postman.setGlobalVariable("variable_key", "variable_value");

10、Setting an environment variable  (设置一个环境变量)　　

postman.setEnvironmentVariable("variable_key", "variable_value");

11、Status code:Code is 200 (判断状态码)　　

tests["Status code is 200"] = responseCode.code === 200;

12、Status code:Code name has string (检查code name 是否包含内容)　　

tests["Status code name has string"] = responseCode.name.has("Created");

13、Status code:Successful POST request (成功的post请求)　　

tests["Successful POST request"] = responseCode.code === 201 || responseCode.code === 202;

14、Use Tiny Validator for JSON data (验证器)　　

　　

var schema = {
　　"items": {
　　"type": "boolean"
　　}
　　};
　　var data1 = [true, false];
　　var data2 = [true, 123];

　　tests["Valid Data1"] = tv4.validate(data1, schema);
　　tests["Valid Data2"] = tv4.validate(data2, schema);
　　console.log("Validation failed: ", tv4.error);
